Manual Tabular Form

Today, I answered an interesting question in the ApEx Forum. Basically, the requirement was to have a tabular form which allows only new records to be edited. Tabular forms are a powerful feature but also something the most of the ApEx developers have a problem with. The manual from the How-To's is outdated, confusing and it is also incorrect in several issues. Also, there are not many other resources in the community dedicated to the problem of operating with tabular forms. This is why I decided to create an example showing several important techniques for mastering this topic. I also posted the most of the code you need to get it working that way:

- highlighting selected rows
- validating the checksum
- disabling columns not allowed for editing
- adding rows to tabular form (one or multiple)
- operating with apex_item package

See the example in my Demo Application. If you want to see more, you may send me an email and join the group of 250 registered users of my Workspace.



A similar example was one of the topics in our training two weeks ago and was created by Patrick Wolf and myself.
